Classic 16-bit platformer Sonic the Hedgehog 2 is this week's Xbox Live Arcade release, and will go for 400 Microsoft points (GBP 3.40 / EUR 4.65) when it launches around 10am BST tomorrow.
As detailed on Xbox.com, Sonic 2 features the usual range of unlockable Achievements, online multiplayer options and enhanced graphics and sound.
Don't worry though, because SEGA insists it "stays true to the original, but takes full advantage of high-definition graphics, with enhanced sound effects". Phew. And of course there'll be a demo.
In the meantime, why not check out our Sonic the Hedgehog review to see how the first game turned out on Live Arcade?
